Global Herbs LymphBlend is designed to provide nutrition to assist the normal process in which this fluid moves around the body, especially around the legs. Any horse can get puffy legs from time to time because of changes in the way that fluid under the skin circulates. If you are getting a lot of fluid accumulating after a wound, then you will need the quick input of your local vet straight away. However for general support in healthy horses and to assist the work of your local vet, with his or her permission, this formula can be very useful.
